Astronomers trace the Small Magellanic Cloud’s unusual stellar motions to a past cosmic encounter.

Astronomers believe that there have been three generations of stars in the universe. The first, which are yet to be seen directly, were made of just hydrogen and helium. The Sun is among the last ones ...

A newly discovered star suggests tiny relic galaxies like Pictor II preserved the chemical material created by the universe's ...

The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy ...

Astronomers have discovered a flattened structure of matter around the Milky Way that explains the unusual motion of nearby galaxies.

Chinese astronomers have identified a pair of young, blue "baby star clusters" on the outskirts of the Milky Way, approximately 45,000 light-years from Earth. They have named the twin clusters Emei-1 ...

The Small Magellanic Cloud (SMC) is one of the Milky Way's closest galactic neighbors—a small, gas-rich galaxy visible to the ...

The Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing a transformation visible from the southern hemisphere. This change is due ...

New observations of L 98-59d, a member of the five-planet system L 98-59, suggest it harbors a vast global magma ocean that traps sulfur deep inside, forming a previously unrecognized class of ...

Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial ...

Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the elements—and how massive supernovae reshaped the cosmos ...

Astronomers have discovered a unique molten planet, L 98-59 d, orbiting the red dwarf star in the Volans constellation. It features a perpetual ocean of magma and a sulfur-rich atmosphere, making it a ...
